Trismelasmos neirai sp. n. (Lepidoptera, Cossidae, Zeuzerinae) from Solomon Islands

Abstract

The article describes Trismelasmos neirai Yakovlev & Hulsbosch sp. nov. distributed in Solomon Islands (Guadalcanal Island). The article has two illustrations. The new species is most close to T. vavilovi Yakovlev, 2022, from which is differs in a series of characters: the uniform coating of gray and light grey scales on the upper surface of the fore wing (in T. vavilovi, there is a light portion in the middle of the fore wing and a small light-brown portion on the fore wing basally); the smooth abdominal margin of the valve (in T. vavilovi, the abdominal margin of the valve has a deep notch on the border between the basal and medium thirds); the phallus, strongly curved along all its length (in T. vavilovi, the phallus is almost straight).
